EPA vial, also known as an Environmental Protection Agency vial, is a type of sample vial specifically designed for environmental analysis, particularly in the context of water and soil testing. The EPA has established certain standards and regulations for environmental testing, and EPA vials are designed to meet these requirements.
EPA vials are typically made of inert materials, such as borosilicate glass, to minimize interactions between the sample and the vial. They are available in different sizes, typically ranging from 20 mL to 40 mL, to accommodate various sample volumes.

EPA vials are those that meet the requirements of the US Environmental Protection Agency (EPA) for the testing of potentially harmful environmental contaminants in water or soil samples. To be used for environmental analysis, EPA vials must be clean and free of substances that might influence the analysis.

The production process of high-performance total organic carbon (TOC) sample bottles is kept clean, and the workshop and production process are guaranteed to be clean, which can reduce instrument background and ensure top-level system performance for low-level monitoring.

We provide the protection of PTFE and the resealing ability of silicone with our septa and seals to fit our autosampler crimp top vials. This seal includes a two sided PTFE septa with silicone in the center. Caps are made of high quality polypropylene, Caps have the profile of a crimp or snap closure for compatibility with robotic autosamplers, Pre-assembled septa reduces the chance of contamination during sample preparation, while saving sample preparation time in the lab.

The manufacturer’s lot number for each component of this product is tracked until all procedures are completed at which time a final lot number is assigned and documented. A randomly selected collection of vials from each completed lot are submitted to an independent validation laboratory for quality control purposes to confirm that the TOC vials comply with the quality specification. The vial, closure and dust cover undergo comply with stringent quality standards and specifications.
